A self-control number is a number that indicates a character's susceptibility to some mental disadvantages. The lower the self-control number, the greater the likelihood that the character will give in to that particular temptation. However, in most cases a player simply choose to indulge in whatever behavior the disadvantage covers.
The self-control number modifies the point value (rounded down) of the disadvantage:
- Resist quite rarely (roll of 6 or less): 2 x listed cost.
- Resist fairly often (roll of 9 or less): 1.5 x listed cost.
- Resist quite often (roll of 12 or less): listed cost.
- Resist almost all the time (roll of 15 or less): 0.5 x listed cost
